Andover produces a non-radioactive dielectric multilayer coating designed to reduce the reflection of Germanium substrates in the infrared. Reflection is reduced from 36% per surface to less than 1% per surface.

For your convenience and economy, we offer the filters in two standard sizes: 25 mm and 50 mm dia. However, we can produce custom sizes and shapes, as well as custom optical characteristics. Contact our expert on the right for a quotation.
